Answer:
2.5% change when rounded to the nearest tenth
Step-by-step explanation:
The Formula for measuring change over time:
P=N−O/O⋅100
P is the percent change
N is the New Value - 20.6 for this problem
O is the Old Value = 20.1 for this problem
First subtract the new value from the old value (you should get 0.5)
Then, divide that number by the old value (you chould get a really long decimal)
Then, multiply that number by 100 (You should get a number like 2.48756 etc.)
Lastly, round it up to the nearest tenth (2.5)
